Y 16 Claims. This invention relates in general to packages for smallarticlessuch as' tablets, 'pills or buttons, l

or powdered or granulated material, or liquid or paste, one object oftheinvention being to provide a package that shall include a novel andimproved construction and combination of a bag or envelo'pe for thearticles or material having an initially sealed and tamper-prooffoldable closure, and a foldable cover for enclosing the envelope or bagand comitructedto cooperate with said foldable closure after the closurehas once been unsealed or opened so as to hold the4 closure in closedposition when the cover is folded to enclose the bag or envelope and torelease said foldable closure when the cover is unfolded for access tothe bag or envelope, whereby `the bag can be repeatedly opened andclosed easily and quickly. and shall be held rmly closed. l

Another `object is to provide a package that l shall-include a novel andimproved construction and combination of a bag or envelope formed of 4flexible material, and a foldable cover formed of ing a modlncation ofthe invention and showing thebag sealed. and l 4Figure 9 is a similarview showing the bag y opened and inverted for removing vthecontentsfrom the bag.

Specifically describing the form of the invention shownin Figures l to 5inclusive, the package comprises a bag,` envelope or like container Aformed of suitable material. 'preferably thin and flexible sheet orstrip materiall such as paper, "cellophane," Plioiilm," metallic foil,cloth or the like, especially sheet material which itself isthermoplastic and canbe softened by heat-i or has a thermoplastic orfusible coating, `so that the juxtaposed layers of material can be fusedor .caused to adhere together by application of heat and pressure, orwith glue. to form a seal. As

shown, the bag comprises a single'strip of marelatively stiffer materialfor enclosing and protecting said bag or envelope, with one end of saidbagor envelope permanently connected adjacent oney end of` said coverand the bag or envelope provided with a fold intermediate its lengthwith which the other end of the' foldable cover shall cooperate to holdthe bag or` envelope ilat in proper position and against crumpling inthe cover.

Other objects, advantagesand results of the invention will appear fromthe following description in conjunction with the, accompanying drawingsin which v Figure 1 is a perspective view of a package con- -vstructedin accordance withmy invention and showing the cover opened.

The bag A is associated with a cover B'which is foldable around the bagto enclose and protect the bag and also to receive printed matter suchadvertising material. Preferably thecover is formed of a single strip ofmaterial relatively stiffer than material of which the bag A i`s formed,

and is folded at 2 aroundvone end of the bag and -secured to the bag asby adheslveor by heat and p crimping where the material of whichl thebag is formed is thermoplastic.

VThe other end of the bas Ah'as a neck portion I and is initially sealedor closed in any suitable manner as 'by crimping l. so that the bag istamper-proof. VThe bag may be opened by tearing the material across theneck as` at lil to form an opening Il, and after the baghas once beenopened, it is closable by transversely folding the bag as at 5 inwardlyVof the opening Il.

'Ihe body portion of the cover strip lies along or is juxtaposed to oneside 4of the bag A, and the cover strip has a second fold I to receivethe fold I of the bag and to form a cover flap Cthat 4is hingedlyconnected 'att 6 to the body portionof the cover strip. The flap C' isfolded at 1 to form two hingedly connected sections I and 9, the latterof which isV adapted to be arranged in side-by-side relation to' andbeneath the section I as the cover is folded about the package. Thesection B is of a sizel to cover the side of the package opposite thebody portion l. of the cover strip, and the section 9 is voffsuch 4sizethat its free end. edge lil may separably enter the fold l of the bag soas to stretch and u hola sst the bag between said :oid and the ypoint ofconnection 2 of the bag with the coverand at the same time hold thetransverse Afold I of the bag between said end edge and the fold 6 ofthe cover when the cover is folded around the bag to enclose it. as mostclearly shown in Figure 4 of the drawings.

Suitable means may be provided for holding the closure flap C in thiscover-closing position, but as shown the marginal end portion II of thecover strip beyond the fold 2 is inspaced yrelation to the side of thebag A so as to releasably receive the fold 1 of the closure ilap whenthe cover is folded around the package, to hold the-closure flap againstunfolding, as shown in Figure 4.

With this construction it will be observed that the fold '2 of the coverstrip closes and reenforces one end of the bag A, the cover protects therelatively thin and weak material of the bag, the cover flap firmlyholds the closure fold 5 of the bag against unfolding, and the section 9of the closure flap also serves in the nature of a spring follower andstretches and holds the bag in proper position and against crumbling ordisplacement in the cover. After the bag has been opened initially byremoval of the tearing flap 30, the bag can be closed and openedrepeatedly by simple folding and unfolding of the cover flap C and thefold 5 of the bag.

A modification of the invention is shown in Figures 6 and 7 where thebag or envelope D is formed of two separate sheets I2 of material thatare crimp sealed together along the longitudinal margins, as at I3, andone end, as at Il. The other end of the bag is initially closed as by acrimped seal I5 which provides a tearing flap like the flap 30. Thecover of this form of the package is of the same structure andcooperates with the bag D in the same manner as in the form shown inFigures 1 to 5 inclusive.

Figures 8 and 9 illustrate another modification of the bag wherein thebag E is formed of two superposed layers of packaging material, such asPuoi-lim, that are crimp sealed or bonded together along their marginalportions as at I6 to form a receptacle to hold small articles such aspellets F, or liquid, paste, powdered material, etc. The sealed orbonded portions I6 of the layers of material are so shaped as to providea discharge or pouring neck I1 for the bag and to provide a tearing flapI8 which can be torn across the neck to form a discharge or pouringorice I9. 'I'he bag E is enclosed in a cover G that may be substantiallyidentical in construction with the cover B.

The bag is initially sealed to enclose the co tents and make the packagetamper-proof, andwhen it is desired to open the bag, the flap I8 is tornoff, after which the bag may be inverted as shown in Figure 9 forremoval of the contents. The discharge neck 'Il provides a restricteddischarge for the contents lof the bag so as to restrict the flow of thecontents of the bag through the orifice I9. After the bag has once beenopened, it can be again closed and then repeatedly opened and closed byfolding of the bag in thecover as described in connection with the formof the invention shown in Figures 1 to 5 inclusive.

Other modifications in the structure and combination of the bag andcover will occur to those skilled in the art as within the spirit orscope of the invention. f
